We present record power of 3.7 W from a CW Cr:ZnSe laser pumped directly with a diode laser. Power >1.5 W over the tuning range of 2200–2600 nm is presented. A first-of-kind demonstration of electro-optic tuning is also presented.

The weaponization and dissemination of biological warfare agents (BWA) constitute a high threat to civilians and military personnel. An aerosol release, disseminated from a single point, can directly affect large areas and many people in a short time

We have developed a novel multiline infrared laser for dual-mode coherent/direct-detection Doppler/DIAL measurements of wind velocity and 3-D aerosol and chemical concentration. 2.02 μm and 3.4-3.6 μm tunable output are generated by a highly effici

Tunable single-frequency sources in the 2-4 micron wavelength region are useful for remote DIAL measurements of chemicals and pollutants. We are developing tunable single-frequency transmitters and receivers for both direct and coherent detection lid

A standard grating-tuned extended-cavity diode laser is used for injection seeding of a tapered semiconductor laser/amplifier. With sufficient injection power the output of the amplifier takes on the spectral characteristics of the master laser. The

Linewidth reduction of an extended cavity diode laser at 657 nm was accomplished by negative feedback to an intra-cavity ADP crystal. High resolution (170 kHz wide) saturated absorption signals were recorded of the calcium intercombination line which

At NIST in Boulder we have been pursuing an active research program developing diode-laser technology for scientific applications. Commercial diode lasers are readily available in a few wavelength bands in the red and near IR region of the spectrum.

We have built a coupled master oscillator and a slave oscillator optical parametric oscillator (OPO) system that provides single-frequency, pulsed radiation in the midwave infrared (MWIR). The direct-diode-pumped master OPO provided narrow-band (
